Specification of Letterslatent I Patented Ma 24, 1921.

Application filed. September i. e g. serial n gsasea of use in various other connections, the object being to provide a Windlass by means of which shrunken barrels or tanks may be tightened.

Another object of the invention is to provide a Windlass which may be placed at various positions upon the outside of the barrel and in which the ratchet operating mechanism is positioned out of the'way of the tightening rope or cable, thereby preventing undue wear upon the latter or damage to the ratchet mechanism.

To this end the invention includes a pair of plates held in spaced relation by spacing rods or bolts and having mounted for rotation between them a winding drum, the

ratchet mechanism being so mounted upon one trunnion of the drum upon the outer side of the plates as to'be out of the path of the rope or cable. The plates are provided with curved flanges along one of their edges for contact with the periphery of the barrel.

The invention also includes the following novel construction, combination and arrangementof parts to be hereinafter more fully described and illustrated in the drawings, in which:

Figure 1 is a view in side elevation of a fragmentary ortion of the barrel-illustrating the appllcation of the invention;

' Fig. 2 is a top plan view of the Windlass detached from the barrel;

Fig. 3 is an enlarged sectional view on the line 3-3 of Fig. 1; and

Fig. 4 is a detail perspective View ofone of the bearing plates.

Referring to the corresponding parts, the improved Windlass includes upper and lower bearing plates drawings in detail,- wherein like characters of reference denote.

outer rounded surface of the barrel. These plates are secured together in spaced relation through the medium of bolts or rods 12, spacing ends 13 being provided upon the rods for the purpose of holding the plates in position. One edge of each of the plates is curved, as shownat 14 and this curved edge is provided with anangularly disposed fiange 15, the latter bein adapted to fit the transverse curvature o the barrel.

Mounted between the plates 10' and 11,

is a drum 16,.the outer surface of which is concaved, each end of this drum is provided with atrunnion 17, which passes through bearing openings 18 in each of the plates 10 and 11. The trunnion '17 which passes through the plate 10 has secured thereon a ratchet wheel 19, the said wheel being mounted upon the trunnion 17 upon the side of the plate opposite the drum 16. Also mounted upon the plate 10 is a dog 20, a bracket 21 being spaced from the plate and a dog 20 mounted within this space upon a pivot 22. The dog 20 is adapted to engage the teeth of the ratchet wheel 19,

a spring 23 serving to hold the dog in such engagement. Mounted for free rotation upon the trunnion 17 above the ratchet wheel 19 isa lever 24, this lever being mounted between the wheel 19' and the ratchet wheel 25 fast upon the trunnion 17. The ratchet wheel 25 is engaged by a dog 26 carri d by the lever 24, this dog being also forced into engagement with the ratchet wheel by a spring 27. The outer end of the lever 24 carries an operating handle 28.

The drum 16 is provided with a trans verse opening 29 for the passage of a rope or cable, the latter being adapted to encircle the barrel so that rotation of the drum through the medium of the ratchet mechanism will cause the tightening of the rope or cable so as to draw the sides of the barrel tighter together. The hoops may then be tightened by tapping them with a ham-v mer or other tool to move them upon the larger circumference of the barrel.

The invention is susceptible of various changes in its form, proportions and minor 105 details of construction and the right is reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention, what is claimed is In combination with a flexiblegtension element to be passed around a eooperage article for drawing the staves together, a frame having laterally extended faces to bear on segmental parts of said article at opposite sides of the plane of the passedaround tension element, a drum rotatably mounted in said frame, said tension element being connected to said drum for winding thereon to contract said element .allel with said planexof said passed-around tension element, and a ratchet mechanism operatively connecting said operating handle to said drum.

In testimony whereof I afiii; my signature.
